Notes
If untrusted users have access to a database that has not adopted a
secure schema usage pattern, begin each session by removing
publicly-writable schemas from search_path. One could, for example, add
options=-csearch_path= to connstr. This consideration is not specific to
dblink; it applies to every interface for executing arbitrary SQL commands.

or schema qualify the function:
select logger.some_func();
